This study was carried out to obtain information about the valuable combination and concentration to produce good plants of cut gerbera flowers of 19 domestically - bred gerbera cultivars. BA and kinetin combination is more effective than NAA and BA combination to produce good plants and mass propagation of domestically - bred gerbera cultivars. Normally almost of 19 cultivars, mass propagation was more effective on the medium containing 1.0 ㎎/L BA + 0.5, 1.0 ㎎/L kinetin. But some cultivars, ’Sunnyeo’, ’Oksaem’, ’Piny’, and ’Pink Light’, vitrified plants were induced on MS medium high level of BA concentration(BA 1.0 ㎎/L), in comparison with those on the medium with low level of BA(0.1 ㎎/L). Fresh and dry weight, more effective on the medium containing BA 0.5 ㎎/L + Kinetin 0.1, 0.5 ㎎/L. Anatomical investigation of vitrified leaf, stomata of vitrified leaves were circular and inflated, whereas those of normal leaves.
